Benefits of technology

[0006]In view of the above drawbacks, the present invention is to provide a way of adjusting the voltage by means of a rotary wheel. In this way, each time the user can read only one voltage-adjusting numeral, thereby avoiding the user from reading the wrong numeral.

Problems solved by technology

However, since all exposed numerals of the voltage scale 202 are of small size, the user may often read the wrong numeral and thus may push the pushing button 10 to the wrong position.
As a result, the user will get confused whether the adjusted voltage output is in a correct position.

Embodiment Construction

[0015]The technical contents and detailed description of the present invention will be described with reference to the accompanying drawings.

[0016]Please refer to FIGS. 2 to 4. As shown in these figures, the present invention provides a power supply with adjustable outputted voltage. The power supply has a casing 1. The interior of the casing 1 is provided with a circuit board 2 having AC / DC power input processing circuit in which only AC (or DC) exists or both AC and DC exist simultaneously. In the present invention, a power supply having two input voltages is illustrated. The circuit board 2 is electrically connected with a voltage-adjusting knob (rotary switch) 3, an AC power input cable 4, a DC power socket 51, a DC power input cable 5, a DC power output cable 6 and a DC power output connector 8.

[0017]The voltage-adjusting knob 3 is a voltage adjuster for the AC / DC power processing circuit. A rotary rod 31 of the voltage-adjusting knob 3 is provided with a rotary wheel 7. The su...

Abstract

A power supply with adjustable outputted voltage includes a casing, a circuit board, a voltage-adjusting knob and a rotary wheel. The casing is provided thereon with a window, and the circuit board is disposed in the casing. The circuit board is electrically connected to AC / DC power input processing circuit in which only AC (or DC) exists or both AC and DC exist simultaneously. The voltage-adjusting knob is electrically connected on the circuit board. The rotary wheel is provided thereon with a plurality of voltage-adjusting numerals. The voltage-adjusting numerals are located to correspond to the window of the casing and are displayed in the window.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a power supply, and in particular to a power supply with adjustable outputted voltage.[0003]2. Description of Prior Art[0004]A power supply with dual-input power sources has an AC power input and a DC power input, and it converts these two inputted power sources into a DC voltage output for use. As a result, this kind of power supply can be used indoors or outdoors.[0005]The means of adjusting the voltage outputted by the power supply with dual inputs shown in FIG. 1 is a slide switch that is operated by linear movement. A pushing button 10 of the switch is exposed to the outside of a casing 201 of the power supply 20. A voltage scale 202 is printed on the casing 201 at a position corresponding to the pushing button 10. When the user pushes the pushing button 10 linearly, he / she can adjust the voltage output. However, since all exposed numerals of the voltage scale 202 are of small size,...
